Answer:
21
Step-by-step explanation:
First, let's simplify the inequality

The graph looks like this:
Notice that the white dot is placed above the -6, it is important to include it like that.
Now, as an interval:
15x7=105 years
9x5=45 years for the boys
105-45=60 so 60years girls
60/6=10 60 years divided by the 6 girls
Mean is 10 years for girls
Answer:
The correct option is y ≤1/3 x – 4
Step-by-step explanation:
If you look at the attached graph you will see that the inequality is the shaded area below the solid line.
The slope of the line is positive which is 1/3.
The y intercept is equal to -4
Thus the inequality must be:
y ≤1/3 x – 4
Therefore the correct option is:
y ≤1/3 x – 4 ....
Answer: Point C
Step by step: P is 3 spaces away from 0 and C is 3 spaces away from 0. Opposite of each other.
